You might as well be saying that it's perfectly fine to host a discussion board about child porn if you're not actually hosting the pictures. And you would be completely wrong about that too. Keep in mind that in the US and several other countries, the operators of torrent link sites have gone to jail even if their site didn't actually host any content. So what makes you think that a discussion board talking about where to download illegal content would be exempt from the law? It's a slippery slope because you can talk about the torrent clients and such, but the moment you cross over into actually sharing specific information on how to break the law (where and how to download copyrighted content) then you yourself are now an accessory to committing a crime. And if the host of the server knows about this content and doesn't put a stop to it, then they are also accountable. In the case of reddit, they have a huge legal team and the admins of a channel might be able to skate away, but on lemmy every server host is on their own and directly responsible for the content their server provides. Sorry if you don't like it, but your feelings don't change the law.
